For Android Users I stumbled across AirSpot
. Run it up on an Android Phone or Tablet (make sure you then put in your Spotify Account Details into AirSpot) and then ANY Spotify App (PC/Andriod/iOS) on your network will then see all DLNA and Airplay devices as a connectable Device... including
the Axiom Air.
From what I can see all streams are pushed via your Phone/Tablet running AirSpot to the target device, so it will flatten the battery pretty quickly unless you have it plugged into power (So I'm running it on my Galaxy View which is on AC Power all the time). Nice.
